ABSTRACT
The monetary values for emissions and resource use that were primarily intended for product and process development. Products and processes are here to be understood in a wide meaning. It could be a window cleaning service, or it could be a new production plant. To illustrate the use of monetary values of environmental impacts in product and process development. To improve the precision in the analysis, the data contributing most to the uncertainty in ranking can be found by the indicator E/s, where E is the change can do in a value before the ranking of alternatives changes, and s is the uncertainty. The larger the E/s, the more it contributes to the uncertainty. To find out how certain the ranking between the alternatives are a Monte Carlo simulation can be made.
